Kerr Street Underpass Project

Improving how people move, through and within Oakville

The Town of Oakville, through its transportation master planning process, identified the need to rebuild and widen Kerr Street between Speers Road and Wyecroft Road, including the building of a new underpass at the Lakeshore West GO line. The town is partnering with Metrolinx to move forward with this project and complete it faster.


This project will improve traffic flow in the area, and allow Metrolinx to deliver increased GO service levels on the Lakeshore West line using electric trains. For details visit the Metrolinx website.


In spring/summer 2018, Metrolinx will issue a Request for Proposal (RFP) to build the Kerr St. underpass along with other infrastructure required to expand GO service on the Lakeshore West line. The winning bidder will be selected in late 2018 and will be responsible for the detailed design, planning, staging and construction of the Kerr Street underpass.

The next public meeting will take place in late 2018. Preliminary work on the project will start in 2019 with construction of the underpass starting as early as the spring of 2020. The work will take up to three years to complete. The current road alignment will remain in place during construction while we build the new road to the west.


This is a major engineering project and the town and Metrolinx will work hard to reduce the impact of construction on businesses, residents and local traffic as much as possible throughout project.

Construction and Design

The Kerr Street Underpass Project is a critical part of the town's Transportation Master Plan and will include:

  • building a new underpass at Kerr St. and the Metrolinx railway;
  • widening Kerr Street from Speers Road to just north of the QEW to allow for two northbound and two southbound lanes, including dual soutbound left turn lanes and a right turn lane at Speers Road; northbound and southbound left turn lanes at Shepherd Road, and a northbound left turn lane at the intersection with Wyecroft Road
  • shifting the road alignment westerly to keep the underpass as far away from the Sixteen Mile Creek top of bank

The new underpass will also allow Metrolinx to deliver increased GO service levels on the Lakeshore West line using electric trains.

Streetscape Design

This portion of the project focuses on the selection of street furnishings and other streetscape elements in the area north of Speers Road. The town intends to incorporate the selected elements into a conceptual streetscape strategy for future reference and consideration for streetscape improvements within the Kerr Village Growth Area.

The community will be invited to review and provide input into streetscape element selection at two upcoming public meetings.
